From what I can tell everything should be working.
The oscillator is working. I can get a 15.74khz signal at the HO grid pin 5 and 3, and you can hear it singing.
After everything warms up, I can hear a faint fizz at the CRT anode and in the HV cage. It fizzes again when I turn the set off. If I pull the anode from the CRT it doesn't make the noise. I guess HV is there, but I still cannot feel it on the back of my arm and hand as I pass it by the tube face. I thought I had good continuity on my HV lead to the rectifier, but I'll double check again.
After replacing R96 CRT voltage at pin 10 is around 350v. There is very little change when I disconnect the CRT socket.
Other than that, I'm not sure what else to do here. Perhaps the near dead tube is to blame. I raised the filament voltage to 9 volts on my CRT tester but the emission didn't budge. Its just a cooked tube. I've tried rejuvenation but its just no use.
I guess for now its dead in the water...
